Official title: To amend the Clean Air Act to provide for additional reductions in emissions of sulfur dioxide and oxides of nitrogen in regions contributing to acid deposition in the Adirondacks.

Amends the Clean Air Act to require the Administrator of the Environmental Protection Agency to promulgate regulations requiring reductions in sulfur dioxide emissions from utility units located in subregions contributing to acid deposition in the Adirondacks necessary to limit, by the year 2000, acid deposition rates to a target level at which the acid neutralizing capacity level of surface waters exceeds the level found in a 1984 survey and the maintenance load of sulfur per hectare does not exceed a specified quantity. Requires the Administrator to also promulgate regulations necessary to require utility units in subregions that are major contributors to Adirondack acid deposition to employ, no later than January 1, 2000, reasonably available technology to reduce nitrogen oxide emissions. Describes means allowed for compliance with these regulations. Disallows treatment of emission reductions achieved by compliance with this Act as emission reductions for any other Clean Air Act purposes or as authorizing excess sulfur dioxide emissions under Clean Air Act utility unit allowances.
